I had used ScheduleOnce integrated with Outlook calendar for scheduling appointments and checking availability for about a year without problem. The website is simple to use and configure for users. Once setup, you have a custom URL that you can share with clients and potential clients alike. As long as you set your availability and fill your calendar with personal and business events as well, you can be sure SO will only display truly available times to your clients and prevent scheduling errors.

After a year or so, SO began to allow clients to schedule calls at times my calendar had been marked busy. In addition to this, some scheduled calls would not appear on my Outlook calendar. After searching support and contacting support, it was suggested I uninstall and reinstall the desktop client application. This fixed it immediately but the issue returned again in the future. Support was fast to respond and suggested another technical fix which allowed it to refresh its connection. It was later explored by the support team and an update was issued which has since resolved the problem. It was a frustrating time during this period but SO's support was professional and helped resolve it in a reasonable amount of time.

It's so easy to use, didn't take me 15 minutes to learn it

NONE! I like this app very much! Good job to y'all!

A great calendar management tool compared to sending emails and asking people if a set of times "works for them". Just send them a link and they can pick a time that works from your calendar. Compared to the email route, ScheduleOnce is incredible, and I used it for years.

Calendly has entered the marketplace with a product that is more user-friendly, more human, and has a great free plan (whereas ScheduleOnce has no free plan). When putting these two side by side, Calendly wins on all fronts, which makes ScheduleOnce irrelevant for me, personally.

Right balance between all the important features (practicality) and ease of use (usability).

It would be good if the not yet accepted scheduling requests would not be allowed for the same time slot.

Simple to set up and the integration with my underlying primary calendar is very good.

For what it does I have no complaints, "IF" I wanted to use it as my primary interface for my overall calendar management, I would likely have additional input.
